A thermal insulation plate (), which is manufactured from cellular plastic, and the upper surface of which comprises grooves (), which are arranged in two directions over the area of the entire surface. The thermal insulation plate comprises at least in part of the groove () intersections a spacer () for installing reinforcement, which is formed from thermal insulation material as a fixed part of the thermal insulation plate.

Thermal insulation plate and its use

Disclosed herein are structures for supporting a clamshell- or slider-type portable electronic device such as a notebook computer; personal digital assistant; or wireless telephone. The clamshell- and slider-type portable electronic devices typically have at least two assemblies&#x2014;a first housing assembly, and a second housing assembly containing at least a keyboard. In a clamshell-type electronic device, the first housing assembly and second housing assembly are connected by a hinge and pivot between at least an open position and a closed position. In a slider-type electronic device, the first housing assembly and second housing assembly are connected by a slide connection and slide between at least an open position and a closed position. In portable electronic devices made in accordance with the invention, the keyboard is comprised of a first set of keys and a second set of keys. The keys comprising the first and second sets have touch surfaces configured to receive keystrokes. The touch surfaces of the first set of keys extend above the touch surfaces of the second set of keys. When a portable electronic device having either the clamshell- or slider-type configuration is in a closed position, the combination of the varying heights of the touch surfaces of the keys and cooperating structures in the first and second housings hinders relative movement between the first and second housing assemblies when an external force (for example, due to an accidental drop) is applied to the portable electronic device. The hindering of relative movement helps to protect the portable electronic device from damage.

Support structure for portable electronic device

An antenna is integrated inside a mobile terminal comprising a lid, a base, a hinge element, a keyboard and a screen. The antenna is located inside the hinge element of the mobile terminal. The hinge element containing the integrated antenna connects the base and the lid of the mobile terminal.
